Agency / Department Discount Program

At C&H Precision, our products are designed and manufactured to meet tight tolerances. Installation can be affected by variations in your plate, hardware, optic, and firearm tolerances. For safe installation and to prevent potential damage to any component, we advise dry-fitting all parts before a full installation. If any problems arise during this process, please reach out to our Customer Service via our contact portal.
When making aftermarket firearm modifications, factory components can often become obsolete, particularly when mounting optics on the slide, whether through direct milling or using a plate. Achieving the correct height for low co-witness iron sights depends on factors such as the firearm type, mounting plate, optic, and slide cut. For assistance in determining the appropriate iron sight height for your specific setup, please contact our Customer Service team through our dedicated contact portal.

    Plate functions as it should and is solid. Only thing I don’t like is it is thinner than the factory plate thereby lowering the RMR. The 509MRD LE sights are fairly tall. By lowering the RMR, the rear sight blocks out more of the field of view.

    No complaints. Fits on the FN509 compact just fine.

    Received my plate end of may early June. Plate had a slight bow in it but thought nothing of it. Coating looked fine so I didn’t believe it was bent in the mail. However after installing and having it compress down after installing the red dot and then changing it months later, I noticed the bottom has a slight crack. Not sure if it is the coating or the plate. (Purchased a new reticle this weekend 8/12/23 that was the reason for removal). Disappointed will be in touch with customer service and update this review after

    Bought this for my FN545. I like that the C&H plate is thinner than the plastic plates FN provides. Provides for a better co-witness with the iron sights.
